Universelle Diamantpolierwerkzeuge Mini-Serie (UDBTM)

For when size matters

The latest addition to the Cogsdill Burnishing portfolio is the Universal Diamond Burnishing Tool Mini Series (UDBTM).

Following on from the success of the original UDBT Series, we are pleased to introduce a smaller sibling designed specifically for CNC sliding head lathes (Swiss-type).

Using Cogsdill’s proven diamond insert geometry, our premium range of burnishing tools can achieve low RA surface finishes, by cold flowing the peaks into the valleys in one pass – achieving results not attainable from any other metal removal process.

UDBTM are designed to be adjustable through 180 degrees, which makes them the ideal choice tool for varying component applications where a designated orientated tool is not required.

The quick and simple castellated adjustment makes this the most versatile diamond burnishing tool on the market!

The range has just got bigger
(actually, it’s just got smaller!)

Cogsdill Universal Diamond Burnishing Tool Mini Series (UDBTM) is a compact burnishing solution, with the adjustment head not much bigger than a cent (as shown in the illustration). But don’t let it’s small size fool you, this tool offers huge return on investment.

UDBTM are designed to produce mirror-like finishes on any surface; from carbon steels to tool steels, cast iron to alloys, and most ferrous and non-ferrous metals.

UDBTM offers the flexibility for burnishing outside diameters, tapers and faces to achieve superior surface finishes not achieved by turning alone.

Further more, set up and operation is relatively simple, no special operator skills are required.

As a result, Cogsdill UBDTM offers incredible production efficiencies and cost effectiveness.

There are currently two different models available:

  • UDBTM-S-12 (Square Shank with 12mm section)
  • UDBTM-R-16 (Round Shank with 16mm diameter)

The UDBTM-S-12 is supplied with a clamp plate assembly extending its versatility for varying machine configurations.

Machine tool requirements:

Developed as a solution for burnishing on CNC Swiss-type sliding head machines, this single tool streamlines operations significantly as it can be utilized in either left or right-handed machine configurations, with either round or square shanks to suit tool post or collet installation.

Compatible with many CNC sliding head lathes including:

HBM horizontal boring machine suitable for Cogsdill ZX Tooling

How Universal Diamond Burnishing Tool Mini Series work:

1 Undo the retaining cap head with a hex wrench which will release the castellated housing from its locked position.
2 Rotate the housing to the required angle and then tighten the retaining cap head to secure the tool.
3 The UDBTM is then mounted in the tool post or collet of the desired machine, using the square shank clamp plate assembly if required.
4 The diamond burnishing nib is brought into contact with the workpiece at the centerline of the part and against the surface being finished.
5 Nach der Berührung weitere 0,002 oder 0,003 Zoll (0,05 oder 0,08 mm) zustellen – das der Diamant im Halter abheben kann.
6 Die Federvorspannung drückt den Diamanten gegen das Werkstück.
7 Das rotierende Werkstück wird jetzt mittels Werkzeug Längsvorschub entlang der Oberfläche geführt, um eine spiegelähnliche Oberfläche zu erzeugen.

Alle Diamanten, die Cogsdill bei der Werkzeugherstellung verwendet, werden von De Beers bezogen und entsprechen ihrem Herkunftskodex, um sicherzustellen, dass sie natürlich und konfliktfrei sind und branchenführende ethische Standards erfüllen.

Replaceable Diamond nibs

The Diamond nibs are easily replaced once they have worn. The nibs are interchangeable between all sizes and styles across the UDBT/M series.

2 Make sure that that tool body and holder are clean.
3 Replace the o’rings on the nib, insert the nib into the holder and screw back into the tool body.
4 Re-tighten the retaining nib holder with a wrench.
